Intermittent Service Vehicle Soon (SVS) Light Comes On - keywords BCM calibration cluster control DTC module power speed SVS

This PI has been reinstated due to a high volume of calls to Technical Assistance.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Intermittently the Service Vehicle Soon light may illuminate with no codes, or only a history DTC C0000 stored in the Power Steering Control Module (PSCM). The Service Vehicle Soon (SVS) light can be identified by a picture of a car with a wrench in it. For vehicles built prior to VIN break point 56171611, the SVS may illuminate after the bulb check and remain illuminated until the ignition key is turned off. The following information DOES NOT apply to the Service Engine Soon (SES) light.

If ALL of the following criteria are met, follow the repair instructions below.

1. No codes current or history set in any module or only a C0000 found as a history code in the Power Steering Control Module (refer to Service Bulletin 04-08-47-001 regarding C0000).
2. There are no concerns about erratic steering feel (heavier/lighter than normal).
3. There are no concerns about an erratic speedometer needle.
4. If the concern is "The SVS light came on when the vehicle was started and stayed on after the bulb check until the ignition was turned off". This is not an intermittent illumination "during" a key cycle.

Note: If any of the above conditions are not met, it will be necessary to perform further diagnosis per SI, since other issues may be present.

If ALL of the above Conditions are met, then replace the Instrument Panel Cluster (IPC). The following parts can only be obtained through an Electronic Service Center (ESC).
